摘要
为了得到高精度的磁场测试数据,需要对磁力仪的不正交误差进行校正。通过分析磁力仪产生误差的9参数校正因子,结合建立的误差校正数学模型,并以Sheffield大学研发的GATBX遗传算法工具箱为开发工具,对磁力仪不正交误差进行校正。实测数据证明,该算法能够有效的降低磁力仪的不正交性带来的误差影响。
in order to get high precision magnetic field test data, need not orthogonal error correction of magnetometer. Through the analysis of the 9 parameters of magnetometer to produce error correction factor, combine to establish the mathematical model of error correction and the university of Sheffield r＆d GATBX genetic algorithm toolbox for development tools, the magnetometer is not orthogonal error correction. Experimental data show that this algorithm can effectively reduce the error brought by the magnetometer not orthogonality.
